Abstract

L'invention concerne un dispositif d'alimentation électrique, ainsi qu'un véhicule et un procédé d'alimentation électrique associé. Le véhicule peut comprendre : un dispositif de charge embarqué (300), une batterie rechargeable (400) et un dispositif d'alimentation électrique (200), le dispositif d'alimentation électrique (200) comprenant : un circuit CC-CC (201) et un commutateur (202), une extrémité de sortie du circuit CC-CC (201) étant couplée à une extrémité du commutateur (202) et servant de premier port d'alimentation électrique A du dispositif d'alimentation électrique (200), et l'autre extrémité du commutateur (202) servant de second port d'alimentation électrique B du dispositif d'alimentation électrique (200); et le premier port d'alimentation électrique A étant utilisé pour être couplé à une première charge dans le dispositif de charge embarqué (300), et le second port d'alimentation électrique B étant utilisé pour être respectivement couplé à une seconde charge dans le dispositif de charge embarqué (300) et à la batterie rechargeable (400). L'état du commutateur (202) est commandé, de telle sorte qu'il peut être assuré que de l'énergie est fournie à toutes les charges importantes dans le cas d'une seule et quelconque faille d'un des types suivants : le dispositif de charge embarqué (300) est court-circuité, le circuit CC-CC (201) est défectueux et la batterie rechargeable (400) est défectueuse et défaillante. Des charges importantes basse tension d'un véhicule peuvent toujours assurer la fiabilité de l'alimentation électrique de secours, ce qui permet d'améliorer la fiabilité de l'alimentation électrique redondante par les charges basse tension et d'assurer la sécurité du véhicule.
